Scientists are studying to prove whether vitamin B12 methylcobalamin deficiency increases the risk of dementia, which is a disease that damages older people neurons.
  • During the synthesis of DNA, methylcobalamin works together with folate. methylcobalamin Deficiency in either of the two decreases the production rate of red blood cells. These two nutrients are essential to protect yourself from cardiovascular disease. In preserving DNA integrity also, they play a vital role.

If your stomach, small intestine or pancreas doesn’t function properly, then you can suffer from intestinal malabsorption. Regular usage of antacid also leads to methylcobalamin deficiency. Because the body utilizes the acid secret from the stomach to separate methylcobalamin from food, but antacid obstructs it.
